It's really not that difficult. I live on basically the same budget (also a student in Germany), as do many others I know. I have a washing mashine which is over ten years old, but still works fine. Got it from somebody who bought a new one for free. My tv is really old, I got it from a friend who got it some years before that from their grandmother. About once a year I buy a new jeans and 1-2 tshirts.
